Using the Chain Saw

6.5.1 Before Operation
WARNING
￭ Misuse or unauthorized use may result in personal injury
and property damage.
– Use the chain saw only as described in this
instruction manual.
￭ For proper assembly of the bar and chain:
– Read and follow the instructions on mounting the
guide bar and chain, @ 16.2.1.
￭ The chain, guide bar and sprocket must match each other
in gauge and pitch. Before mounting or replacing:
– Read the information on guide bar and chain
combinations, @ 28.1.
– Read and follow the instructions on kickback and
other reactive forces, @ 7.
– Select the shortest bar that will meet your cutting
needs. Longer bars add weight and may be more
difficult to control.
￭ Proper tension of the chain is extremely important to
maximize cutting performance and reduce the risk of
personal injury from chain breakage, derailment or
reactive forces:
– Never cut with a loose chain. If the chain becomes
loose while cutting, switch off the motor, engage the
chain brake and remove the battery from the chain
saw before tightening the chain. Never attempt to
adjust the chain while the battery is inserted.
– Read and follow the chain tensioning instructions,
@ 16.3.
– Always make sure the chain sprocket cover is
tightened securely after tensioning the chain in order
to secure the bar. Never start the chain saw with the
chain sprocket cover loose or missing.
– Check chain tension once more after tightening the
chain sprocket cover.

6 IMPORTANT SAFETY INSTRUCTIONS
– Check chain tension periodically thereafter at
regular intervals (only after engaging the chain brake
and removing the battery).
￭ Using a chain saw that is modified, damaged, improperly
adjusted or maintained, or not completely and securely
assembled can lead to a malfunction and increase the risk
of serious personal injury or death.
– Never operate a chain saw that is modified,
damaged, improperly maintained or not completely
and securely assembled.
– Always check your chain saw for proper condition
and operation before starting work, particularly the
retaining button, trigger switch, trigger switch
lockout, front hand guard, chain brake and cutting
attachment.
– Ensure that the trigger switch and trigger switch
lockout move freely and always spring back to the
locked position when released. The trigger switch
must not engage until the trigger switch lockout is
depressed.
– Never attempt to modify or override the controls or
safety devices in any way.
– If your saw or any part is damaged or does not
function properly, take it to your authorized STIHL
servicing dealer. Do not use the saw until the
problem has been corrected.
￭ Before inserting the battery:
– Check the contacts in the battery compartment for
corrosion or other foreign matter and keep clean.
– Never insert or use a malfunctioning, damaged,
cracked, leaking or deformed battery.
– Read and follow the instructions on switching on the
chain saw, @ 19.1.
